FIELD OF THE DISCLOSURE

Some embodiments of the disclosure relate to a method and computer program product for graphical user interface (GUI) organization control for robotic floor-cleaning devices.

BACKGROUND

Robotic floor-cleaning devices are an increasingly popular solution for keeping floors clean in residential and commercial settings. Many robotic floor-cleaning systems generate maps of their environments using sensors to better navigate through the environment. However, such maps often contain errors and may not accurately represent the areas that a user may want the robotic floor-cleaning device to service. Further, users may want to customize operation of a robotic floor-cleaning device based on location within a map. For example, a user might want a robotic floor-cleaning device to service a first room with a steam cleaning function but service a second room without the steam cleaning function. A need exists for a method for users to adjust a robotic floor-cleaning map and control operations of a robotic floor-cleaning device based on location within the map.

SUMMARY

Some aspects provide a method and computer program product for graphical user interface (GUI) organization control of robotic floor-cleaning devices.

In some embodiments, a map of a workspace is generated from data acquired by sensors positioned on a robotic floor-cleaning device. In some embodiments, the map is sent to a user interface on a device such as a smartphone, computer, tablet, dedicated remote control, or any device that may display outputs from the system and receive inputs from a user. Through the user interface, a user may make changes to the map boundaries and select settings for the robotic floor-cleaning device to carry out in user-identified areas of the workspace. In some embodiments, user adjustments are sent from the user interface to the robotic floor-cleaning device to implement the changes.

The terms “including”, “comprising”, “having” and variations thereof mean “including but not limited to”, unless expressly specified otherwise. The enumerated listing of items does not imply that any or all of the items are mutually exclusive, unless expressly specified otherwise. The terms “a”, “an” and “the” mean “one or more”, unless expressly specified otherwise.

Various embodiments are described hereinbelow, including methods and techniques. It should be kept in mind that the invention might also cover articles of manufacture that includes a computer readable medium on which computer-readable instructions for carrying out embodiments of the inventive technique are stored. The computer readable medium may include, for example, semiconductor, magnetic, opto-magnetic, optical, or other forms of computer readable medium for storing computer readable code. Further, the invention may also cover apparatuses for practicing embodiments of the invention. Such apparatus may include circuits, dedicated and/or programmable, to carry out tasks pertaining to embodiments of the invention. Examples of such apparatus include a general-purpose computer and/or a dedicated computing device when appropriately programmed and may include a combination of a computer/computing device and dedicated/programmable circuits adapted for the various tasks pertaining to embodiments of the invention.

The term “user interface” as used herein refers to an interface between a human user or operator and one or more devices that enables communication between the user and the device(s). Examples of user interfaces that may be employed in various implementations of the present invention include, but are not limited to, switches, buttons, dials, sliders, a mouse, keyboard, keypad, game controllers, track balls, display screens, various types of graphical user interfaces (GUIs), touch screens, microphones and other types of sensors that may receive some form of human-generated stimulus and generate a signal in response thereto.

Various methods currently exist for generating maps of an environment. Simultaneous localization and mapping (SLAM) techniques, for example, may be used to create a map of a workspace and keep track of a robotic device's location within the workspace. The mapping of a device's environment is not included in the scope of the invention, therefore a detailed description thereof is not provided.

In some embodiments, once a map is established, it may be sent to a user interface. Maps may be sent to a user interface at any stage; they do not need to be complete. In some embodiments, through the interface, a user may view the map and take any of a variety of actions. In embodiments, a user interface may be provided through a software application on a computer, tablet, smartphone, or a dedicated remote control. In some embodiments, a user may adjust or correct the map boundaries within the user interface by selecting all or part of a boundary line using a cursor, pointer, stylus, mouse, the user's finger, a button or buttons, or other input device on the user interface. In some embodiments, once a boundary line is selected, a user may be provided with various options, such as, but not limited to, deleting, trimming, rotating, elongating, redrawing, moving in a left direction, moving in a right direction, moving in an upward direction, moving in a downward direction, etc. In some embodiments, a user may be given the option to redraw a boundary line using a cursor, pointer, stylus, mouse, the user's finger, a button or buttons, or other input devices.

In some embodiments, maps generated by robotic devices may contain errors, be incomplete, or simply not reflect the areas that a user wishes a robotic floor-cleaning device to service. By adjusting the map, a user may improve the accuracy of the information that the robotic device has about its environment, thereby improving the device's ability to navigate through the environment. A user may, for example, extend the boundaries of a map in areas where the actual boundaries are further than those identified by the system, or trim boundaries where the system identified boundaries further than the actual or desired boundaries. Even in cases where a system creates an accurate map of an environment, a user may prefer to adjust the map boundaries to keep the device from entering some areas.

In some embodiments, data may be sent between the robotic floor-cleaning device and the user interface through one or more network communication connections. Any type of wireless network signals may be used, including, but not limited to, radio signals, Wi-Fi signals, or Bluetooth signals. In some embodiments, map data collected by sensors of the robotic floor-cleaning device is sent to the user interface, where a user may make adjustments and/or apply or adjust settings. In some embodiments, changes made by a user in the user interface are sent to the robotic floor-cleaning device through the one or more network communication connections.

In some embodiments, robotic floor-cleaning devices may have a plurality of tools that can be used concurrently or independently, such as, but not limited to, a suction tool, a mopping tool, and a UV light for killing bacteria. In some embodiments, robotic floor-cleaning devices may also have various settings, such as a deep cleaning setting, a regular cleaning setting, speed settings, movement pattern settings, cleaning frequency settings, etc. In some embodiments, a user is enabled to adjust all of these settings through the user interface. In some embodiments, a user may select with a cursor, pointer, stylus, mouse, the user's finger, a button or buttons, a keyboard, or other input devices any portion of the workspace and select one or more settings to be applied to the area.

FIG. 1 illustrates an example of a process for creating a two-dimensional map and utilizing an interactive user interface. In a first step 100, the system collects data about the environment with sensors positioned on the robotic floor-cleaning device. In a next step 101, the system generates a two-dimensional map of the workspace based on the collected data. As mentioned previously, any available methods may be used to create a two-dimensional map of the environment, including, but not limited to, simultaneous localization and mapping (SLAM) techniques. In some methods, measurement systems, such as LIDAR, are used to measure distances from the robotic device to the nearest obstacle in a 360 degree plane in order to generate a two-dimensional map of the area. In a next step 102, the two-dimensional map is sent to the user interface via one or more network communication connections. In a next step 103, the system checks for changes made by a user on the user interface. If any changes are detected (to either the map boundaries or the operation settings), the method proceeds to step 104 to send the user changes to the device. If no changes to the map boundaries or the operation settings are detected, the method proceeds to step 105 to continue working without any changes.

FIG. 2 illustrates an example of a process for customizing robotic device operation through a user interface. In a first step 200, a user selects the area of the workspace map in which he or she wants to designate robotic device operation settings. A user may select any size area; the area selected could be comprised of a small portion of the workspace or could encompass the entire workspace.

In a next step 201, a user selects desired settings for the selected area. The particular functions and settings available may be dependent on the capabilities of the particular robotic floor-cleaning device in question. For example, in some embodiments, a user may select any of: cleaning modes, frequency of cleaning, intensity of cleaning, navigation methods, driving speed, etc. In a next step 202, the selections made by the user are sent to the robotic floor-cleaning device. In a next step 203, a processor of the robotic floor-cleaning device processes the received data and applies the user changes.

FIG. 3A illustrates an overhead view of an exemplary workspace 300. This view shows the actual obstacles that may be detected by a robotic floor-cleaning device. The outer line 301 represents the walls of the workspace and the rectangle 302 represents a piece of furniture. FIG. 3B illustrates an overhead view of a two-dimensional map 303 created by a robotic floor-cleaning device of the workspace 300 shown in FIG. 3A. Because the methods for generating the map are not 100% accurate, the two-dimensional map generated is approximate and not perfect. A robotic floor-cleaning device may devise navigation plans based on the generated map, and thus performance may suffer as a result of imperfections in the generated map. A user may desire to correct the boundary lines to match the actual obstacles. FIG. 3C illustrates an overhead view of a user-adjusted two-dimensional map 304. By changing the boundary lines of the map 303 (shown in FIG. 3B) created by the robotic floor-cleaning device, a user is enabled to create a two-dimensional map of the workspace 300 (shown in FIG. 3A) that accurately identifies obstacles and boundaries in the workspace. Furthermore, as discussed previously, a user may identify areas within the two-dimensional map to be treated in specific ways. By delineating a portion 305 of the map, a user may select settings for that area. For example, a user may identify the area 305 and select weekly cleaning, as opposed to daily or standard cleaning, for that area. In a like manner, a user may define the area 306 and turn on a mopping function for that area. The remaining area 307 may be treated in a default manner. Additionally, in adjusting the boundary lines of the two-dimensional map, a user is permitted to create boundaries anywhere desired, regardless of whether an actual boundary exists in the workspace. In the example shown, the boundary line in the corner 308 has been redrawn to exclude the area near the corner. The robotic floor-cleaning device will thus be prevented from entering the area. This may be useful for keeping a robotic floor-cleaning device out of areas that a user does not want the device to service. For example, a user might exclude areas from a map with fragile objects, pets, cables or wires, etc.

FIG. 4 illustrates an example of a user interface 400. In the example shown, the user 401 has delineated sections of the workspace 402 to be serviced in different ways by the robotic floor-cleaning device 407. The user has delineated four sections: 403, 404, 405, and 406. The user may select the settings of the robotic floor-cleaning device within each section independently of the other sections using the user interface. In the example shown, a user uses his or her finger to manipulate the map through a touchscreen; however, various other methods may be employed depending on the hardware of the device providing the user interface.

Additionally, in some embodiments, a real-time robotic floor-cleaning device manager may be provided on the user interface to allow a user to instruct the real-time operation of the robotic floor-cleaning device regardless of the device's location within the two-dimensional map. In some embodiments, instructions may include any of turning on or off a mop tool, turning on or off a UV light tool, turning on or off a suction tool, turning on or off an automatic shutoff timer, increasing speed, decreasing speed, driving to a user-identified location, turning in a left or right direction, driving forward, driving backward, stopping movement, commencing one or a series of movement patterns, or any other preprogrammed action.
